Sit on the Left side of the plane for the best views on flights from Kathmandu to Seoul. Takeoff views of the Himalayas are exceptional and unique to this route—the dramatic mountain scenery is worth prioritizing. Landing views at Incheon are good from the right, but the Himalayan departure from the left is the more memorable segment of this flight.

During takeoff from Tribhuvan International (KTM), sit on the Left side for the best views. Kathmandu typically departs runway 02/20 depending on wind. Left seats face north on northbound departures, giving direct views of the Himalayan range as you climb. The snow-capped peaks rise dramatically from the Kathmandu Valley floor within the first 10-15 minutes of flight. Notable sights include: Langtang Himal (north), Shivapuri Ridge (immediate north of valley rim), Kathmandu Valley urban sprawl (beneath), Bagmati River valley (winding through city).

When landing at Incheon International (ICN), sit on the Right side for the best views. Incheon typically uses runways 03L/03R or 15L/15R. On approach from the southwest, right-window seats face northwest toward Seoul and the Han River estuary. You'll see the Incheon Bridge, Yellow Sea coastline, and Seoul's urban sprawl across the water before touchdown. Notable sights include: Incheon Bridge (distinctive cable-stayed structure), Han River estuary and tidal mudflats (brown/gray), Seoul skyline (distant, north), Yellow Sea coastline (west).

The flight from Tribhuvan International (KTM) to Incheon International (ICN) takes Approximately 3 hours 15 minutes.

The flight path crosses the Tibetan Plateau at cruise altitude (around 35,000 feet). You'll pass over the eastern edge of the Tibetan Plateau with its characteristic brown, barren terrain and sparse settlements. The Yangtze River's upper reaches may be visible as a thin line in good visibility. As you approach China's eastern border, you'll transition over increasingly green, cultivated terrain in Sichuan and Hubei provinces. The Yellow River valley becomes visible in the final approach to Korean airspace. At cruise altitude, individual landmarks are difficult to distinguish, but the broad geographic transition from high plateau to lowland river valleys is apparent.
